Quick question that I may not need the answer for! After purchasing a Phantom from a private individual, how do you change the 'registration' at DJI? Im going to an estate auction saturday that has 2 DJI drones listed (Haven't yet been able to find out which version). They are really buried in the listing and I'm hoping that I won't have too much competition! If I do manage to snag one (or both), I will want to register the change of ownership.
